    md/bitmap: add new 'space' attribute for bitmaps. · 6409bb05
    NeilBrown authored
    If we are to allow bitmaps to be resized when the array is resized,
    we need to know how much space there is.
    
    So create an attribute to store this information and set appropriate
    defaults.
    
    It can be set more precisely via sysfs, or future metadata extensions
    may allow it to be recorded.
